When I start glxgears (3 rotating gearwheels), the screen remains ON (unblank), when I switch to console (cntr-alt-fx), the error remains: in the console the screen also blanks/unblanks. Sorry, I am no Linux expert and my english is out "of training". I usualy start my system with kernel 3.14 (3.14.4-2.g0de0f93) so that the monitor remains ON, but then I miss the features of newer kernels.... By the way: the monitor is a SAMSUNG SyncMaster P2250 and it doesn't go in powersave mode, it only blanks. Possibly the problem has to do with a new power saving feature since kernel 3.15, because on havy load of the HD3200 by using glxgears the screen remains ON?? Reproducible: Always Steps to Reproduce: 1. start the system with kernel 3.15.0-1.g9194b64 (and newer) 2. wait few seconds after login (or wait at login prompt) 3. Actual Results: the screen blanks and unblanks in a randomly matter (between 2 and 10 seconds) KDE and console (ctrl-alt-fx) Expected Results: the screen remains ON Motherboard: Gigabyte GA-MA78G-DS3H (Version 1) with final update F9 (not the newest, I know!!) with "Embedded" Graphic ATI HD3200 Processor: AMD Athlon(tm) II X4 615e RAM: 8 GB Monitor: SAMSUNG SyncMaster P2250 (DVI-D connected) jupiter:~ # egrep 'EE|WW' /var/log/Xorg.0.log [ 26.222] Current Operating System: Linux jupiter 3.16.2-1.gdcee397-desktop #1 SMP PREEMPT Sun Sep 7 04:40:17 UTC 2014 (dcee397) x86_64 (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
